Description

  TECHNICAL FIELD The present invention relates to a fixing metal fitting used when an article is loaded on a loading platform of a transporting machine such as a truck and transported, and is secured to the loading platform by using a cord-shaped body such as a rope or a belt.

  When various items are loaded on the loading platform of the transporting machine and transported, the articles may move due to shaking or vibration during transportation and may be damaged or dropped by contacting other loaded items or loading platform. . Therefore, in order to prevent damage, measures are taken such as covering the article with a cushioning material such as a blanket, or securing and fixing the article to the luggage carrier using a string-like body.

  In particular, when carrying relatively heavy items such as various machines such as agricultural machines and work machines, furniture such as chests and tables, or office equipment, when they come into contact with the cargo bed or drop. High risk of. Therefore, when loading and transporting articles on the loading platform, it is important to firmly fix and maintain the fixed state during transportation, that is, to secure stability.

  As described above, when loading and fixing a heavy load on the bed of a transport machine, work is often performed with gloves on as a safety measure. In addition, since the article to be conveyed is secured to the loading platform by the string-like object, the article can be moved by swinging at the time of transportation by bundling the string-like object at a plurality of positions of the article and pulling in multiple directions. Even so, a stable fixed state is maintained. Hereinafter, the transported article is also referred to as a “transported article”.

JP, 2000-320526, A

  Since the work of fixing the article to the bed of the transport machine or unraveling it after transport is a fine work, for example, workability is poor in a state where gloves are worn, which requires time and labor.

  Patent Document 1 describes a metal fitting having two hooks having different radii of curvature for fixing an article on a bed of a truck. Since the metal fitting has two hooks, it is not necessary to make a loop in the middle of the rope, which has been conventionally made. Therefore, there is a description that the connecting portion with the metal fitting is advantageous in that the trouble of tying and unraveling each time it is transported can be omitted, and that the article can be easily secured.

  However, since the metal fitting has only two places connected to the cord-shaped body, the pulling force from the cord-shaped body to one metal fitting may not be sufficient. Further, since one metal fitting can be pulled only in one direction, a large number of metal fittings are required to perform pulling in a plurality of directions necessary to stabilize the fixed state.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a fixing metal fitting that can easily fasten an article to a luggage carrier and can obtain a stable fixed state.

The fixing metal fitting of the present invention is a metal fitting for fixing an object to be fixed, and the metal fitting is composed of an annular body and three or more hooks movably connected thereto, and the hook is bent. A metal linear member having a wire diameter of 5 mm or more, a connecting portion that is movably connected to the annular body, a hook portion that engages with an object to be fixed, and a body that exists between the connecting portion and the hook portion. And an opening angle of the hook portion in plan view is 10 ° to 80 °.
Here, the object to be fixed means an article and a string-like body used for securing the article.

  The ratio of the cosine length of the claw portion to the maximum length of the hook is 0.2 to 0.8.

  The body is characterized by having a length adjusting mechanism whose length can be changed.

  The fixing metal fitting of the present invention is a metal fitting for fixing an object to be fixed, and the metal fitting is composed of an annular body and three or more hooks movably connected thereto, and the hook has a bent wire diameter. A metal linear member of 5 mm or more, including a connecting portion that is movably connected to the annular body, a hook portion that engages with an object to be fixed, and a body portion that exists between the connecting portion and the hook portion, Since the opening angle of the hook portion in plan view is 10 ° to 80 °, the article can be easily fastened to the luggage carrier even with gloves on, and a stable fixed state can be obtained.

  Since the ratio of the cosine length of the claw portion to the maximum length of the hook is 0.2 to 0.8, the string-like body is maintained while maintaining the ease of engaging the hooked portion with the object to be fixed. It becomes difficult to disengage from the hook, and the object to be fixed can be fixed more stably. As a result, it is possible to further reduce the risk such as the fall of the transported object from the loading platform of the transportation machine.

  Since the length of the body can be changed, the body can be retightened and the tension can be relieved by adjusting the length of the body. As a result, the articles can be more firmly bound when fixing, and the string-like body can be easily unwound when loading and unloading from the loading platform, so the stability and workability of the fixed state are improved. Further improve.

It is a top view of the fixing metal fittings of this invention. It is a top view of a hook. It is a top view of a hook provided with a length adjustment mechanism. It is a figure of the state where the article was bound by the fixing metal fittings.

  An embodiment of a fixing metal fitting according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a plan view of a three-pronged fixing fitting 1. As shown in FIG. 1, the fixing fitting 1 is composed of an annular body 2 and three hooks 3. These are made of stainless steel and can be formed by processing a linear member having a predetermined wire diameter. The ring-shaped body 2 has a continuous ring-like shape by bending the linear member into an annular shape and then connecting both ends thereof by welding. The three hooks 3 connected to the ring-shaped body 2 have the same structure and can move freely while being connected to the ring-shaped body 2.

  The fixing metal fitting needs to have such strength that it will not be deformed when pulled by a string-shaped body or the like. Therefore, the material of the linear member is made of metal, and stainless steel, steel, aluminum or the like can be used. From the viewpoint of aesthetics and corrosion resistance, stainless steel is preferable, and from the viewpoint of strength, steel is preferable. Further, the linear member is a linear member having a predetermined thickness, and the wire diameter is 5 mm or more. When the weight of the article to be fixed is large, the load applied to the fixing metal fitting is also large. Therefore, it is preferable to use the fixing metal fitting composed of a linear member having a larger wire diameter of 7 mm or more. The cross-sectional shape of the linear member can be freely selected from a circular shape, a polygonal shape, etc., and is not limited to a specific shape. In the case of a circular shape, the force is not concentrated at the points of contact between the engaging part where the object to be fixed and the hook part of the hook engage, or the engaging part of the connecting part between the annular body and the hook, so the object to be fixed It is preferable that the object or the fixing metal piece is less likely to be damaged or deformed.

  FIG. 2 is a plan view of the hook 3, which is a main constituent member of the fixing fitting. 2A shows each part of the hook 3, and FIG. 2B shows lengths and angles of predetermined parts for explaining the structure of the hook 3. The hook 3 is composed of a connecting portion 4 that is connected to an annular body (see FIG. 1), a hook portion 6 that engages with a string-shaped body or an article, and a body portion 5 that exists between the connecting portion 4 and the hook portion 6. To be done.

  The connecting portion 4 is formed by bending the end portion of the linear member so as to connect to the annular body. The end portion of the bent linear member may be in a closed shape by being connected to the root portion of the bending by welding or the like, or may be in an open shape as it is bent. The body 5 may have a bent shape or a straight shape. Moreover, the trunk | drum 5 may have the length adjustment mechanism mentioned later.

  The hook portion 6 includes a claw portion 7 having a return structure for engaging with a fixed object. As described above, the hook portion 6 and the connecting portion 4 are respectively bent, and the respective planes formed by the bent portions may be on the same plane, or the long axis direction of the body portion 5 may be used as the rotation axis. You may have a twisted relationship. When the plane formed by the hook portion 6 and the plane formed by the connecting portion 4 are on the same plane, when the hook portion 6 is engaged with the object to be fixed, the claw portion 7 can be easily oriented toward the worker, Excellent in performance.

  The claw portion 7 is bent at a predetermined angle. The angle of bending of the claw portion 7 in the hook portion 6 (hereinafter referred to as “opening angle θ of the hook portion”) is 50 °. Here, the opening angle θ of the hook is an angle formed by three points, that is, the tip 8 which is the tip of the claw 7, the crown 9 of the hook 6, and the crown 10 of the connecting portion 4. Of the measurement points at both ends of the hook 3 when the lengths of the tops 9 and 10 are measured so that the length of the hook 3 is maximized, the end on the side of the hook 6 is the top 9 and the connecting portion. The end on the side of 4 is the crown 10. Further, the length between the crown 9 and the crown 10 when the length of the hook 3 is measured to be the maximum is referred to as "maximum length L of the hook 3".

  The opening angle θ of the hook can be selected in the range of 10 ° to 80 °. By setting this range, for example, even when gloves are worn, the fixing metal fittings can be easily engaged with the fixing target such as a string-like object or article, which is excellent in workability and stabilizes the fixing target. Can be fixed to. If the opening angle θ of the hook portion is smaller than 10 °, it becomes difficult to hook the fixed object on the hook 3 during fixing, and if it is larger than 80 °, the hook easily comes off the fixed object after fixing.

  When the opening angle θ of the hook is in the range of 20 ° to 50 °, the stability when fixed is particularly excellent. When the opening angle θ of the hook portion is in the range of 50 ° to 70 °, a relatively wide space is formed between the tip portion 8 of the claw portion 7 and the hook portion facing it, so that the cord-like body is easily hooked, Especially excellent workability. The hook having an opening angle θ of the hook of 50 ° to 70 ° has a problem that the hooked object is likely to come off when used for general purposes such as household use, but it is used as a fixing metal fitting while being pulled by a string-like body. In this case, since the detachability is reduced, it can be preferably used for the application.

  The ratio 1 / L of the cosine length 1 of the claw portion 7 to the maximum length L of the hook 3 is 0.25. Here, the "length 1 of the cosine of the claw portion 7" refers to the length of the cosine at the opening angle θ of the claw portion, which is the distance between the crown 9 of the claw portion 6 and the tip 8 of the claw portion 7. When the ratio 1 / L is in the range of 0.2 to 0.8, the object to be fixed is less likely to come off the hook, and the article can be more stably fixed, which is preferable. As a result, it is possible to further reduce the risk such as the fall of the transported object from the loading platform of the transportation machine.

  If the ratio 1 / L is less than 0.2, the string-like body may easily come off from the hook during fixing. On the other hand, when it is larger than 0.8, the hook portion is too large for the entire hook, so that the fixing metal fitting is difficult to handle and the workability may be deteriorated. When the ratio 1 / L is in the range of 0.2 to 0.3, the workability at the time of fixing and the difficulty of detaching the cord-like body from the hook are excellent in balance, which is particularly preferable.

  The body portion 5 and the hook portion 6 may be coaxially connected straightly, or may be bent and connected. In the case where the hooks 6 are bent and connected to each other, when the hook 6 is hooked on the string-like body and fixed while being pulled, the load by which the claw 7 is deformed and opened (hereinafter, referred to as “withstand load”) can be increased. preferable. When the hook portion is bent and connected to the long axis direction of the body portion 5, it is preferable to set the bending angle within the range of 5 ° to 30 ° because both the load resistance and the resistance to disengagement can be achieved.

  The maximum length L of the hook 3 can be freely selected, but is preferably in the range of 3 cm to 30 cm. If it is shorter than 3 cm, it is too small to be handled easily and the workability may be deteriorated. Further, when the length is longer than 30 cm, the hook portion of the hook is distant from the engaging portion that is engaged with the article to the string-like body, and thus there is a possibility that stability at the time of fixing may be deteriorated. A length L of 5 cm to 15 cm is more preferable because it is easy to handle and has excellent stability when fixed.

  The diameter of the annular body (see FIG. 1) is preferably within the range of 3 cm to 20 cm. If it is smaller than 3 cm, the hook to be connected may be less mobile. Further, when it is larger than 20 cm, it is difficult for the pulling force from the plurality of cord-shaped bodies in a plurality of directions to be transmitted to the article, and the stability at the time of fixing may be reduced. The annular body having a diameter of 4 cm to 10 cm is particularly preferable because it has excellent stability particularly when fixed.

  The body of the hook may have a mechanism whose length can be adjusted. As an example, FIG. 3 shows a plan view of a hook 12 including a body 11 having a length adjusting mechanism whose length can be changed. FIG. 3A is a view in which the connecting portion 4 and the hook portion 6 are accommodated inside the body portion 11 and the hook 12 is shortest. On the other hand, FIG.3 (b) is a figure of the state which made the hook 12 longest. Threads are formed on the connecting portion 4, the hook portion 6, and the threaded portion of the body portion 11, respectively, and the length of the hook 12 can be changed by rotating the body portion 11.

  After the hook 12 of the fixing metal fitting of the present invention is engaged with the article and the other hooks are pulled by the cord-like body to bring each hook into a locked state, the pulling force can be easily reduced by shortening the hook length. Can be increased. Thereby, stability at the time of fixing can be further enhanced. Further, when the article is unwound from the fixed state, by extending the length of the hook 12, the string-like body can be removed without requiring a large force.

  FIG. 4 is a view showing one of a plurality of fixing points when the article 13 is fixed to the loading platform of the transport machine by the string-like body 15 using the fixing metal fitting 1 of the present invention. . The article 13 has a plurality of locking portions 14 on its surface. The plurality of locking portions 14 are connected to the string-like body 15 via the fixing metal fittings 1 and are pulled on the platform by the pulling force received from the string-like body 15. Fixed.

  Specifically, first, one of the three hooks 3 of the fixing metal fitting 1 is hooked to the locking portion 14 existing on the surface of the article 13 by hooking the claw portion. Next, a loop provided at the end of the string-like body 15 is hooked on one of the remaining two hooks 3, and the string-like body 15 is pulled while being bound to a locking portion (not shown) of the luggage carrier. Similarly, the remaining hooks 3 are hooked on the loops at the ends of the string-like body 15 and are pulled together to be fastened to the locking portions of the luggage carrier. The string-shaped bodies 15 hooked on the two hooks 3 may be pulled in different directions to bind to different locking portions on the bed, or may be pulled in the same direction to bind to the same locking portion. .

  While the article fixed on the loading platform is being transported, the loading platform of the transporting machine sways due to unevenness of the road surface or the like, and a force acts on the article in various directions. When two string-shaped bodies are pulled in different directions with respect to one fixing metal fitting, the plurality of locking portions to which the fixing metal fitting is locked are pulled in two directions. As a result, the article is pulled in more directions as compared with the case where the fixing metal fitting of the present invention is not used, and thus the stability at the time of fixing is increased. That is, as compared with the case where each locking part of the article is directly secured with the locking part of the loading platform and the string-shaped body, it can be easily pulled in multiple directions and can be fixed with high stability. Excellent workability when fixed and resistance to shaking during transportation.

  Further, when two strings are pulled in the same direction, the article can be pulled with a stronger force in one direction than when pulled in different directions. However, since the pulling direction is reduced, when the number of locking portions is small, the stability during fixing tends to be low only by the fixing method by pulling. Therefore, if there are many locking parts, or if it is possible to combine with other methods for restricting the movement of the article together with the pulling by the string-shaped body, the two string-shaped bodies can be pulled in the same direction. The method of doing is particularly effective.

  The fixing fitting of the present invention has been described above with reference to the drawings, but the configuration of the present invention is not limited to this. For example, the number of hooks included in one fixing metal fitting is not limited to three as long as it is three or more. The shape and size of each hook may be different. It should be noted that two or more hooks included in one fixing metal fitting may be locked to the plurality of locking portions included in the article. The securing of the article is not limited to the locking portion provided for the purpose of locking, but may be performed on a protrusion such as a handle or a handle included in the article.

  INDUSTRIAL APPLICABILITY The fixing metal fitting of the present invention can easily fix the article to the loading platform or the like even when wearing gloves, and can obtain a stable fixing state. Therefore, the fixing metal fitting for fixing various articles. Widely available as.
